Answer:
x=45 degrees
Step-by-step explanation:
You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.
so 2x+90=180 degrees
so 2x=90 degrees
x=45
Answer:
A
Step-by-step explanation:
Lets dissect the dot plot for information:
1 point = 1 time
2 points = 2 times
3 points = 3 times
7 points = 1 time
8 points = 3 times
9 points = 1 time
10 points = 1 time
Total number of times he gets extra credit points is:
1 + 2 + 3 + 1 + 3 + 1 + 1 = 12 times
Out of which "3" was 3 times
and "7" was 1 times
That would make it
3 + 1 = 4 times
So, out of 12 times in total he gets extra credit points, 4 times is "3" or "7". In percentage, that will be:
4/12 = 0.3333
Multiplying 0.3333 * 100 = <u>33.33%</u>
<u>Answer choice A</u>
#a. y - 5 = 2x
Add 5 to both sides to get,
y - 5 + 5 = 2x + 5
y = 2x + 5
Answer:
Step-by-step explanation:
Two pounds
2 pounds of coffee sells for $3.38
1 pound of coffee sells for 3.38 / 2 = $1.69
Five Pounds
5 pounds of the same coffee sells for $8.50
1 pound of the same coffee sells for $8.50 /5 = 1.70
By a very narrow margin, the 2 pounds of coffee is the better buy.
You would rather pay 1.69 for a pound of something, when your only other choice is 1.70 for the same thing.
